Melissa is designing an experiment to learn what a plant needs to survive. She buys four plants of the same type. Then, she puts two in the light by the window and two in her closet where there are no windows.

Finally, she gives the plants either no water or 100 milliliters of water every week for a month.



Which plant will be the healthiest at the end of the experiment?

plant 3


plant 1


plant 4


plant 2
